Description
Set of eight gongs made of bronze, on a wooden stand in the shape of a Sarimanok(mythical bird, divine messenger). Accompanied by one larger gong (here made of iron, but usually also made of bronze) and two drums. The eight small gongs differ in pitch but the height of the tone is not fixed and can differ per set. The number of large gongs can vary from one to several gongs of different pitch and size. The small gongs are struck with two sticks of appr. 30 cm. length and made of a soft kind of wood, probably of the papaya tree. The large gong is struck with a special beater. The conical drum is struck with a thin piece of bamboo of appr. 40 c.m. length. The cylindrical drum is struck with either the hands or two short wooden sticks.
To indicate the dimensions of the whole set, the length of the Sarimanok-shaped stand is 2,60 mtr, from head to tail. For other dimensions, see the pages of the other instruments of the ensemble (see above).
Remarks
The drums, the stand and the frame are all quite roughly made but elaborately decorated with colourfully painted wood carvings, called 'okiran'.
The stand for the large gong is a copy based on photographs of a stand used by a Maranaw cultural group. The stand was made for the exhibiton 'Ugnayan, music in the Philippines', in 1977 in the The Hague Municipal Museum and in 1978 in the Rotterdam Ethnographic Museum.
